IPC: B01J23/652
Filed: 2004-05-27
Abstract: A tungsten oxide/titanium dioxide photocatalyst coating oxidizes contaminants in the air that adsorb onto the coating into water, carbon dioxide, and other substances. The tungsten oxide forms a in onolayer on the titanium dioxide.  When photons of the ultraviolet light are absorbed by the tungsten oxide/titanium dioxide photocatalyst coating, an electron is promoted from the valence band to the conduction band, producing a hole in the valence band. The holes in the valence band react with water applied on the tungsten oxide/titanium dioxide photocatalyst coating, forming reactive hydroxyl radicals. When a contaminant in the air is adsorbed onto the tungsten oxide/titanium dioxide photocatalyst, the hydroxyl radical attacks the contaminant, abstracting a hydrogen atom from the contaminant. The hydroxyl radical oxidizes the contaminant, producing water, carbon dioxide, and other substances. The tungsten oxide/titanium dioxide photocatalytic coating has low sensitivity to humidity variations.

Title: Chess to the second power
Inventor: LABETTI WALTER
IPC: A63F3/02
Filed: 2005-12-12
Abstract: An improved chess-like game. The game uses a traditional chessboard and basically the same rules. The additional second set of pieces and same rule changes enhances the game. There's a time limit to strategically place the secondary pieces inside of the primary pieces and placed on the board. Primary pieces for each player are the same as traditional chess. Secondary pieces include the same pieces as traditional chess except there is no king. When a primary piece is taken it is removed from the game, the secondary piece is removed from the primary then placed in the same square it was occupying with its primary piece. The piece that took the primary piece returns to the square it was in before advancing. Castling is the same. Using En passant, all pawns can be taken. Only primary pawns have the option of moving two squares on the first move.

Title: Semi-static distribution technique
Inventor: CORBETT PETER F
IPC: G06F3/06
Filed: 2004-11-24
Abstract: A semi-static distribution technique distributes parity across disks of an array. According to the technique, parity is distributed (assigned) across the disks of the array in a manner that maintains a fixed pattern of parity blocks among the stripes of the disks. When one or more disks are added to the array, the semi-static technique redistributes parity in a way that does not require recalculation of parity or moving of any data blocks. Notably, the parity information is not actually moved; the technique merely involves a change in the assignment (or reservation) for some of the parity blocks of each pre-existing disk to the newly added disk.

Inventor: ZAWADZKI ISZTAR I
IPC: G01W1/10
Filed: 2006-09-07
Abstract: The present invention provides a short term weather forecaster for nowcasting using a Numerical Weather Predictor (NWP). The system of the present invention tracks the evolution of differences between NWP and radar based precipitation patterns and adjusts the NWP forecast to account for theses differences. These differences are due to amplitude and phase errors of the NWP, such as model misses, false alarms, intensity errors and position errors. In presuming persistency in time of these errors and in estimating precipitation pattern time evolution due to other weather conditions such as wind motion, the present system corrects the NWP short term predicted patterns to compensate for these errors, thus enhancing nowcasting accuracy.
